Validate Rollup config files (exported JSON or parsed config objects) for output format conflicts, external/bundle mismatches, plugin ordering issues, deprecated options, treeshake settings, and best practices. Supports text, JSON, and summary output formats with CI-friendly exit codes.
# Full validation (all 22+ rules)
python3 scripts/rollup_config_validator.py validate rollup.config.json
# Quick syntax-only check (structure rules only)
python3 scripts/rollup_config_validator.py check rollup.config.json
# Explain config in human-readable form
python3 scripts/rollup_config_validator.py explain rollup.config.json
# Suggest improvements
python3 scripts/rollup_config_validator.py suggest rollup.config.json
# JSON output (CI-friendly)
python3 scripts/rollup_config_validator.py validate rollup.config.json --format json
# Summary only (pass/fail + counts)
python3 scripts/rollup_config_validator.py validate rollup.config.json --format summary
# Strict mode (warnings become errors)
python3 scripts/rollup_config_validator.py validate rollup.config.json --strict
Since Rollup configs are typically JavaScript, this tool validates JSON representations of Rollup config objects. Export your config as JSON or use a wrapper:
# Extract config as JSON from rollup.config.js
node -e "const c = require('./rollup.config.js'); console.log(JSON.stringify(c, null, 2))" > rollup.config.json
python3 scripts/rollup_config_validator.py validate rollup.config.json
Or validate directly from a JSON config file.
